Can We Cool the Planet? FULL SPECIAL | NOVA | PBS America

As global temperatures rise, scientists are exploring solutions from planting trees to sucking carbon out of the air to geoengineering. But would they work? And what are the risks of engineering Earth's climate?

    Save Our Planet - Cool

    On an individual level, the top things we can do to cool down our planet include utilizing the power of the sun; reducing heating, ventilation and air conditioning; make Recycling as a habit, it reduces wastage; you can return the repaired electronics to the respective manufacturers; creating new products from the e-waste; recycle and manage clothes; wash clothes softly for a long life and use less detergent; buy new clothes only when the old one is torn; reducing water usage in our daily activities; move back to the good old habits of hanging washed clothes in the backyard and let them dry in natural air; create a garden by gathering neighbours and town peoples and plant saplings in a spaced manner, to try and forest our town; prefer non-wood products; use carbon readers to calculate the daily carbon emission from your home apparatus and vehicles; prepare food for the required quantity and let’s not make food to reach the waste bin; give a try to vertical farming or terrace farming. So, start farming at your home and become an eco-friendly contributor to this earth; reduce carbon emission from vehicles, start walking start cycling, use on-demand transport, utilize public transit, fix carbon reducers in every vehicle; try to use clean fuel and maintain the vehicle in a good condition by planning your vehicle services; let’s go green and use cloth bags or some degradable and recyclable bags for all our shopping and daily usages. And don’t forget to hold a bag when you go for shopping tomorrow; switching into electric vehicles; we must contribute one tree every year and make the environment green.

    @Stephanie Ellison I live in the city of Toronto, and 35 years ago my Husband and I bought an Arts and Crafts era house. In the yard was an oak tree that is older than the house, an apple tree, and two mulberry trees. We removed the lawns, more than half of the driveway, and the concrete walk. We conditioned the soil with compost from the park (which is available every year). we planted five more fruit trees, and 11 other trees, as well as15 shrubs. The front yard is a forest edge with early indigenous plants, followed through the seasons by other native plants and ground cover. The back yard produces berries, herbs, and vegetables, while the side yard is planted with fiddlehead and asparagus ferns. We shifted from oil to natural gas for heating after changing the windows to double pane argon filled from the original single pane partially leaded windows. We redid the foundation and weeping tiles, and insulated the third floor and roof. Our house cannot be seen from google’s aerial map application from late Spring to leaf fall. Walking along the sidewalk, there is a significant drop in temperature as you arrive at our property in Summer, and we have never needed air conditioning, even on the hottest days. We do not rake the leaves, but allow them to decompose naturally in the front, and tilled into the soil in the back. We had a still pond dug to deny habitat to mosquitoes, but seeded it with water from every healthy natural pond within a one hour drive from home. We made wild bee hotels and bat houses, and kept two hives of honey bees until two years ago. As our yards matured, most of our neighbours did away with their lawns as well, and planted more trees and shrubs. We almost never need to water the gardens (only the food plants occasionally in drought years). Our city has a pollination corridor, (we are in the centre of it), numerous large parks and green spaces, and regulations against cutting trees down. If a tree must be removed for safety…it must be replaced, and the city will provide a medium sized tree to replace it. Many of the high rise buildings in the city core have green roofs, and trees are planted on all sidewalks. The transit system (even for commuters) is good enough that there is little need to bring a car into the city. Viewing Toronto from above, (in Summer), it is hard to realize you are looking at a large modern city. A great deal of effort and money went into keeping Toronto green, and many home owners do what we have (to the degree they are able). There are even cycling stations, where you can take a bike to ride into city centre, and places to drop them off while doing your shopping…and take another to cycle home again. If every urban setting were to do the same, it would make a noticeable difference in both temperature and air quality. I liked your paper, and while I agree with the logic of your reasoning…you will never get people to give up their cars. The best we can hope for there is that people will choose electric or battery powered vehicles painted white. I hope these kind of measures become more popular everywhere.🖤🇨🇦

    Scientifically we can change our climate by how we landscape the Earth with Hardscape material and plants and water. But spiritually if the whole entire population of earth we’re on the same page with their thoughts we can cool the planet overnight. In order for that to happen though everybody has to be on the same page and what I mean by that is everybody has to wake up to who they really are you are souls in a human body that has multiple abilities wake up we can do this!❤

    Exactly, like the Younger Dryas event. Or the normal glacial minimum which drops average global temperatures by ~10 degrees. Right now the temperature is fine. Fossil fuel usage will be finished in the next 50 years because cheaper alternatives like wind turbines solar and batteries will dominate.

    We could ALSO choose NOT to double the human population over the next decade. Instead of seeking even more food production from an already overburdened Planet (both land and sea), we could work toward a balance of population the Earth can sustain. Fertility issues are already much more common than in the past (within my lifetime), and humans are living longer lives. Perhaps the rise of infertility is Nature attempting to reset the balance. Our planet has reset more than five times already, and easily could again. If we do not learn to live connected to everything else…we will ensure our own extinction. The Earth can live and thrive without our species, but WE cannot survive without this living planet, of which we are only a small part among others.🖤🇨🇦

    Are you serious ? The moon and Mars are the only 2 reachable celestial bodies for mankind. Neither have the three essential requirements for human survival. An atmosphere to breathe; water to drink, and food to eat. Mars is too far for other than a few highly trained astronauts to potentially reach at the cost of billions of dollars.and hundreds of scientists and engineers to support their ‘mission’ from Earth [which begs the question: if these scientists are on an unliveable planet Earth how will they execute this mission?] All NASA’s expertise and funds were needed just to send and operate a small Mars Rover. Once reached after 6 months there is no infrastructure, air, water or food other than what their craft can carry. How long could recycled piss last? Even if they could survive a week or two how could they stay warm, breathe, outside their Rocket? All the above logistical problems apply to the Moon. Which just confirms that we have no alternative than to stop our planet Earth becoming unliveable in the near future. Threat from Asteroids, are minimal but rising temperature extremes, floods, sea levels, wildfires, overpopulation, food and clean water are real problems that only mass cooperation, funding and political will can hope to succeed. Climate change seems remote in most 1st world countries but for the poor majority it is already at crisis point. Whether devastating floods, famine, disease, food shortage, overfishing, air pollution and so on. If humans can’t overcome these threats then the last thing we need is for this “intelligence” to survive. I’d say foolishness, short sidedness, greed, and selfishness are more appropriate terms.
